MACHINE FOR ROLLlNG CARRIAGE=TOP IRONS.

SPECIFICATION forming part of Letters Patent No. 373,613, dated November22, 1887.

(No model.)

To aZZ whom it hwy concern:

Be it known that I, FRANK SCHREIDT, of Mansfield, county of Richland,and State of Ohio, have invented a new and useful Improvement inMachines for Rolling Carriage-Top Irons, of which the following is afull, clear, and exact description, reference being had to theaccompanying drawings, making part of this specification.

My invention relates to a novel construction of rolling-machines forrolling carriage-top bow and other irons, and will be fully understoodfrom thefollowingdescription and claims.

In the accompanying drawings, Figure 1 represents a rolling-machine inside elevation embracing my improvements; Fig. 2, a "ertical transversesection through the same on the line was, Fig. 1. Fig. 3 is asideelevation, enlarged, of the grooved and fluted rolls. Fig. 4, is averticaltransversesection through said rolls; Fig. 5, a perspective viewand a transverse section through one of the carriage-irons after it hasbeen subjected to the action of the rolls.

A represents a base-plate or frame of any suitable construction, uponwhich two strong uprights, B and B, are rigidly secured, connected bybars b I), and having vertical slots, the vertical side walls of whichhave suitable ribs or ways, I) b, formed on them, on which are mountedsliding blocks 0, O, 0 and 0 having bearings for the shafts or journalsof the rolls D, D, and D said bearing-blocks being made adjustable onthe ways b b by means of set-screws b to compensate for wear andregulate the pressure of the rolls. On the shafts, at the ends of therollers and between the latter and the blocks 0 O, &c., are collars orblocks E, made adjustable endwise of the shafts by means of screws 6 e,for adjusting the rolls endwise and bringing them into proper workingrelation one with the other. The shaft of the central roll, D, isextended beyond the supporting-standard B at one end, and has secured toit a spur-gear, Fiwhich engages and is driven by means of a pinion, F,fast on a shaft, F, to which motion is imparted in any suitable manner.The shafts of all the rolls extend through the standard B and haveinterrneshing spur-gears F, F*, and F on their the arrows. The severalrolls have each a longitudinal groove formed in it (indicated at g,

g, and g and extending through the portion thereofhaving peripheralgrooves, but leaving ungrooved opposing portions which formrolling-surfaces between the adjacent rolls. The rolls D and D haveformed upon them, between one end thereof and the center of theirlength, a series of grooves, h h, and extending 6o thence to near theother ends of the rolls D and D", the grooves in D being the counterpartof and operating in connection with those opposite them in the roll D,those in the other end of D corresponding to those in the roll'D", andall extending around the rolls and terminating in the longitudinalgroove therein.

The longitudinal grooves g g g serve as guides or gages for theintroduction between the rolls of the ends of the bars or irons I to beoperated upon, whether before or after the knuckles t have been formedthereon, and to leaveaportion thereof adjacent to said knuckle endunrolled or square at i, as shown in Fig. 5. The grooves hand h arepreferably made flatwise in the adjacent faces of the rollers,as servingto more readily free or give clearance to the bars operated upon, andare used (those at h) for bringing the rods into approximately thedesired form, and afterward the bars are passed back between the rolls Dand D" through the grooves or dies h, for still further reducing themetal and giving it the desired shape, which is preferably of the formsubstantially as indicated in Fig. 5, though the grooves may beefdifferent forms for rolling the irons into any desired form. At h asingle pair of grooves is shown (others may be added, if desired) forpassing the irons through, set on edge instead of flatwise, and thesemay be used for the final 9o operation for removing or rolling out anysurplus metal left after the irons have passed through the forminggrooves or dies h and h, but for this last operation I prefer to employrollers of a different construction, described in 5 another applicationof even date herewith.

\Vhere the knucklcsi have been formed upon the bars or rods I prior torolling them, gageplates, having scollops j formed in them to match therounded end of the knuckles, may roe be secured within the grooves, asshown at J, Fig. 3, in the groove 9 of the roller D.

The direction of the movement of the irons in being operated upon isindicated in Fig. 2, it being in one direction between the middle andlower roller for the first operation described, and in the reversedirection between the middle and upper rollers for the second operation.K is a shelf or table upon which the irons fall or are deposited afterthe first operation, and upon which they may be straightened out by theattendant prior to passing them back in the second operation.

,L is a water-supply pipe, and Z 1 adjustable branches thereof, forsupplying water in any desired quantity to the operating portions of theroller-surfaces for preventing undue heating of the same. The pipe L isconnected with a tank or other source of water-supply and is providedwith a suitable means for regulating the flow of the water, asindicated.

The form of the grooves g, g, and 9 will of course be such as to adaptit to the knuckle or other protuberance on theirons to be operated upon.

Having now described my invention, I claim asnew- 1. In a machine forrolling carriage-top and other irons, the longitudinally-grooved rollsprovided with the peripheral rolling-surfaces and intermediateperipheral grooves of the required form terminating in a longitudinalgroove or grooves adapted to form gages for the introduction of theirons to be operated upon, substantially as described.

2; The combination, in a machine for rolling carriage-irons, of therolls D, D, and D, having rolling-surfaces g and grooves g, g,and g", inwhich said peripheral grooves terminate,

arranged and operating substantially as deminatingin longitudinalgrooves g, g, and g,

arranged and operating as described.

In testimony whereof I have hereunto set my hand this 7th day ofJanuary, A. D. 1886.

FRANK SOHREIDT.
